|
STZ-induced diabetes decreases and insulin normalizes POMC mRNA in arcuate nucleus and pituitary in rats.
|
2 |
10233022
|
Proopiomelanocortin (POMC) mRNA in arcuate nucleus (Arc) and pituitary decreased in diabetes and normalized after insulin treatment.
|
3 |
10233022
|
Prodynorphin (proDyn) mRNA increased in diabetes and normalized in the pituitary after insulin but not in the Arc.
|
4 |
10233022
|
Diabetes did not alter proenkephalin (proEnk) expression in the Arc or pituitary, nor dynorphin A1-17 or beta-endorphin in paraventricular nucleus (PVN). alpha-Melanocyte-stimulating hormone (alpha-MSH) peptide levels were decreased in the PVN and normalized following insulin treatment.
|
5 |

|
Diabetes increased Arc neuropeptide Y mRNA, and insulin suppressed this increase.
|
6 |

|
In experiment 2, insulin (2.5 IU/kg sc) daily for 1 wk in normal rats increased Arc POMC mRNA, but not proDyn and proEnk mRNA.
|

|
Also, insulin may influence Arc and pituitary POMC activity in neurons that regulate energy metabolism.
